RING-TRAVELER.

Application filed June 29,1914. Serial No. 847,872.

To all whom it may concern Be it known that I, WILGER T. LANCASTER; acitizen of the United States of America, and a resident of Ashton, inthe State of Rhode Island, have invented a new and useful Improvement inRing-Travelers. of which the following is a specification.

This invention relates to travelers for ring spinning; and it consistsin a beveltop ring traveler of improved construction. and in thecombination of the same with a horizontally flanged ring as hereinafterparticularly described and claimed.

In common with numerous previous improvements, the bevel-top traveler ofthe present invention. is an improvement on the ordinary C-shapedtraveler, the patents for which have expired; and said bevel-toptraveler is therefore shown in contrast to said C-shaped traveler in thedrawings-hereinafter referred to.

The leading objects of this invention are: to reduce the length of thematerial in the traveler, so as to add the weight of the length saved ingreater thickness of metal for longer wear; to render the improvedtraveler better balanced from the contact or bearing at its inner horn,where centrifugal force throws it against the inner flange of the ring;to adapt the improved traveler to wear flatter or more evenly at thispoint of primary. ring contact or hearing; and to adapt the improvedtraveler to be kept in a horizontal or balanced position with a. lighterstrain upon the thread than has heretofore been practicable.

Other objects will be set forth in the general description, whichfollows.

A sheet of drawings accompanies this specification as part thereof.

Figures 1 and 2 are conventional elevations partly in section showing animproved bevel-top traveler in contrast with a C- shaped traveler at thebeginning and end of a ring spinning operation, respectively; Fig. 3represents a magnified section through an I-shaped ring, showing thesaid improved traveler on a larger scale.

Like reference characters refer parts in all the figures.

The horizontally flanged ring represented at a is of an ordinary Isection. See Fig. 3. The bevel-top traveler I) combined therewith is ofimproved construction. An ordinary C-shaped traveler is represented byto like Specification of Letters Patent.

way of contrast at 0. An ordinary bobbin is represented at (Z; thethread eye at e, and one and the same thread running from the thread eye6 through the traveler b or 0 to the bobbin d, is represented at f.

The improved bevel-top traveler b, as

compared with the C-shaped traveler 0, ob-

viously requires a considerably reduced lengthof the ordinary metal fromwhich its blank is cut; and can consequently be made of a given weightfrom thicker material, so as to wear longer. The same is true to agreater or less extent of the improved traveler as compared withtravelers of other known forms. In so reducing the length of the metal,the improved traveler is given the bevel-top shape represented in theseveral figures. In Fig. 3 its inner and outer contact horns arerepresented at 1 and 2, respectively; its bevel top at 3, and itsoutwardly rounded side or end portions connecting said bevel top withsaid horns 1 and 2 respectively, are represented at 4 and 5. The horns land 2 are in line with each other and normally horizontal. The innerhorn 1 adjoins the larger and heavier rounded portion 4. The outer horn2 is about one-third longer than the inner born, but the outer side ofthe traveler including the smaller curved portion 5 is lighter than theinner side, being reduced in weight about one-third as compared withsaid inner side. One effect of so reducing the outer side of theimproved traveler 6 between its outer horn 2 and its bevel top 3 is toadapt the improved traveler to find and maintain an effective balancingposition without any'contact of the outer horn 2 with thering. Previoustravelers as represented at a drop down more or less at the outer side,and occasionally the outer horn comes in contact with the outer side ofthe rim a, and sometimes rubs so hard under centrifugal force as to cutinto the side of the ring I or to draw the temper of the traveler.

The improved bevel-top traveler b is designed and adapted to run in thebalanced position in which it .is shown in the accompanying drawings,whether the bobbin be empty as in Fig. 1 or full as in Fig. 2, andwhether the ring be in its uppermost position, as shown at the top ineach of these figures, or in its lowermost position, represented at thebottom in Figs. 1 and 2. In said balanced position, the horns 1 and 2 ofthe bevel-top traveler b are horizontal as thread f keeping the. entirelength of said inner horn 1 in contact with said ring flange 1. All therest of the improved traveler,

in its said balanced position, vis free from contact with the ring, andthe revolving traveler is thus adapted to run lighter and smoother, aswell as with a flatter and consequently a longer Wear, as compared withsaid previous forms represented at e. Owing to said saving-in wear, agiven weight of the im roved bevel-top traveler will last 100% onger ascompared with said old forms; and running lighter, weight for weight,makes it possible to run travelers three or four numbers heavier-than ispossible withother forms for agiven size of thread; a relatively lightstrain on the thread sufiicing to control a givenweight of traveler.Insuring a flat wear on the inner horn 1 of the improve'dtraveler b isalso advantageous in new of the fact that the uneven wear of the-innerhorn due to the tilting over of old forms of traveler at the outer sideof the ring a, as represented at. 0, extends into' the bend between theinner horn and the inner side vof the traveler, .where strength is mostessential; and sometimes to those portions of the inner side of thetraveler which contact with the thread, causing. them to cut the thread.

The extremity ofthe elongated outer horn 2 contacting with the outerside of the ring a prevents the reducedside or end5 of the improvedtraveler b from coming in contact with the outer flange 2 of the ring'atthe instant when the 'splnning machine 1s bein stopped or started andthe traveler'is pulle inward by the thread. At all other times traveleristhrown outward by j centrifugal orce; When so pulled inward,

Having thus described saidimprovement,
